Fullstack Developer at PLANT-MY-TREE
PLANT-MY-TREE®-per-order
The application enables Shopify merchants to automatically place tree-planting orders for every incoming order. By integrating ecological contributions directly into the purchase process, the manual effort for tracking and billing reforestation initiatives is eliminated. The system increases transparency for end customers through real-time visualizations of the ecological impact directly in the storefront. The architecture is based on a modular monolith with Spring Boot in the backend and an integrated React app inside the Shopify admin area. The solution uses webhooks to capture order data in an event-driven way and integrates the weclapp ERP system for automated monthly invoicing. An app proxy mechanism provides dynamic statistics such as CO2 compensation and planted trees without any performance loss for the merchant shop.
Tasks:
- Design of the modular software architecture based on Spring Modulith to ensure high maintainability
- Development of the event-driven business logic for evaluating Shopify orders via webhooks
- Implementation of automated invoicing by connecting the weclapp REST API
- Building the frontend using React Router and Shopify App Bridge for native integration
- Design of the database model and implementation of the persistence layer with JPA/Hibernate and Prisma
- Integration of internationalization processes for global use in the frontend and email communication
- Automation of deployment processes using Docker and GitLab CI/CD

About the technology
What Node.js is
Node.js is a JavaScript runtime for building server-side software. It is used for APIs, real-time apps, background workers, and services that need fast I/O and simple JavaScript across the stack. Strong experts know where Node.js fits best and where another runtime is a better choice.
What it ships
- REST and GraphQL APIs
- Real-time chat, dashboards, and live feeds
- Microservices and backend-for-frontend layers
- Serverless functions and event-driven jobs
- Streaming tools and file-processing services
Core ecosystem
Node.js work usually sits with npm or pnpm, Express, NestJS, Fastify, and TypeScript. Skilled professionals also handle linting, testing, logging, and deployment setups. They know how to keep package choices lean and avoid dependency sprawl.
When companies bring in freelancers
Companies often need outside Node.js experts when a product team must move fast, untangle legacy code, or add new API layers without slowing delivery. This is common in e-commerce, media, logistics, and B2B software teams in Dusseldorf that need flexible support. Freelancers also help when internal staff are focused on other systems.
What strong specialists do
A strong Node.js specialist writes clean asynchronous code, understands event loops, and keeps services stable under load. They review architecture, improve error handling, and shape code that is easy to test. They also work well with front-end, DevOps, and product teams.
Good project fit
- Startups building the first production backend
- Teams modernizing older Node.js services
- Companies adding integrations, queues, or webhooks
- Products that need quick collaboration with JavaScript teams
- Remote or on-site work when clear communication matters
Frequently asked questions
Questions about Node.js? Start with the answers below.
Node.js is used for APIs, real-time features, background jobs, and services that need quick input and output handling. It is a common choice for products built with JavaScript on the client side and on the server side. Many teams also use it for small services, gateways, and event-driven workflows.
Node.js is often chosen when a team wants one language across the stack or needs strong support for real-time interactions and many concurrent connections. Python is often preferred for data-heavy or scripting-focused work, while Java is common in larger enterprise systems with stricter platform standards. The right choice depends on the product, team, and long-term maintenance needs.
A strong Node.js freelancer usually knows TypeScript, API design, testing, Git, and deployment basics. Experience with Express, NestJS, Fastify, databases, and message queues is often valuable. Good communication matters too, especially when the work touches other teams.
A Node.js project with a simple API may need only one experienced specialist for setup, delivery, and review. More complex systems need someone who can handle architecture, security, scaling, and maintenance. The key is not the title, but proven work on similar systems.
Yes, Node.js is a strong fit for real-time apps such as chat, live status updates, collaboration tools, and dashboards. Its event-driven model works well when many small events must be handled quickly. For heavy CPU tasks, a specialist should plan worker processes or other supporting services.
Yes, many Node.js specialists work remotely with teams in Dusseldorf and across Germany. Remote work fits API delivery, bug fixing, and feature development well when requirements are clear. On-site time can help during discovery, handover, or when several local teams must align quickly.
Look for clear code, solid test coverage, and a calm approach to errors and performance. A good Node.js professional can explain architecture choices in plain language and can point to services they improved, not just frameworks they used. Review how they handle async flow, logging, and package hygiene.
Teams often compare Node.js with Deno, Python runtimes, Java platforms, or Go services. Deno may appeal when security and built-in tooling matter, while Go is often considered for highly efficient services. The best option depends on the product shape and the skills already in the team.
